This application is an example of searching the Flickr API for photos in Swift. Notably, it uses a UISearchDisplayController and the async callback pattern. See https://kyleclegg.com/blog/swift-flickr-search.

• Clone the repo and run FlickrSearch.xcodeproj
• No pod install or carthage update needed -- the only external library, SDWebImage, has been added to the project directly
• Create a Flickr API key and replace placeholder with key in FlickrProvider.swift

Images are retrieved by hitting the Flickr API.

• Search Path: https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=FLICKR_API_KEY&tags=SEARCH_TEXT&per_page=25&format=json&nojsoncallback=1
• Response includes an array of photo objects, each represented as:

{
    "farm": 8,
    "id": 15981410640,
    "isfamily": 0,
    "isfriend": 0,
    "ispublic": 1,
    "owner": "28339853@N03",
    "secret": "a0d5006167",
    "server": 7564,
    "title": "Chi shark week"
}

We use the farm, server, id, and secret to build the image path.

• Image Path: https://farmFARM.staticflickr.com/SERVER/ID_SECRET_m.jpg
• Example: https://farm8.staticflickr.com/7564/15981410640_a0d5006167_m.jpg
• Response object is the image file

• If you want to quickly test this out you are free to use this demo API key (0461b2b85aee5a025189ce3eed1aff6b), but I recommend replacing with your own API key from Flickr
